What is the flare on the Ace tube that connects to the valve block? Is it a push connect flare? One of mine has a bit of rot right at the block and I'd like to replace the section that mounts to the block and tie it in to line that runs to the rear ram with a steel compression fitting. It looks like a 3/8 GM fuel line has the correct flare. I recently had to replace the high pressure ACE pump hose and just had a 3000psi hose made up at the local hydraulic shop that I tied into the steel line with a 3/8 compression fitting.
